# Configure a dial access control rule for dialer access group 1.

<RouterA> system-view

[RouterA] dialer-rule 1 ip permit

# Assign an IP address to interface BRI 1/0, enable C-DCC, and configure the dial strings

for calling Router B and Router C.

[RouterA] interface bri 1/0

[RouterA-Bri1/0] ip address 100.1.1.1 255.255.255.0

[RouterA-Bri1/0] dialer enable-circular

[RouterA-Bri1/0] dialer-group 1

[RouterA-Bri1/0] dialer route ip 100.1.1.2 8810052

[RouterA-Bri1/0] dialer route ip 100.1.1.3 8810063

b. Configure Router B:

# Configure a dial access control rule for dialer access group 2.

<RouterB> system-view

[RouterB] dialer-rule 2 ip permit

# Assign an IP address to interface BRI 1/0, enable C-DCC, and configure the dial string for

calling Router A.

[RouterB] interface bri 1/0

[RouterB-Bri1/0] ip address 100.1.1.2 255.255.255.0

[RouterB-Bri1/0] dialer enable-circular

[RouterB-Bri1/0] dialer-group 2

[RouterB-Bri1/0] dialer route ip 100.1.1.1 8810048

c. Configure Router C:

# Configure a dial access control rule for dialer access group 1.

<RouterC> system-view
